SASH OR DOOR FASTENER.

SPECIFICATION forming part of Letters Patent No. 333,240, dated December 29, 1885.

Application filed June 4, 1885.

To all whom it may concern:

Be it known that I, CHRISTOPHER LONG- BOTTOM, a subject of the Queen of England, residing at Bradford, York, England, have invented new and useful Improvements in Sash-Fasteners, which improvements are also applicable to door and other fasteners, of which the following is a specification.

This invention relates to sash or door looks or fasteners; and it consists in the construction of the fastener or lock, substantially as hereinafter fully described.

In the accompanying drawings, Figures 1 and 2 are opposite side elevations of my improved sash or door lock or fastener, a portion of the same being shown in section in Fig. 2, and the meeting-rails of the sashes being shown in section in both figures. Fig. 3 is also a side elevation showing the locking plate or latch fully thrown open. Fig. 4 is a face or plan view showing aslight modification of the latch and lockingplate, and Fig. 5 is a top plan view of the locking-plate.

A and B, Figs. 1, 2, and 3, indicate the meeting-rails of a pair of window-sashes, and O a supporting-plate of metal secured to sashrail A, on which plate is formed a standard, D, Figs. 2 and 3, the upper face of which is inclined to an angle of or about forty-five degrees. To the inclined faced of said standard D is hinged or pivoted a locking-latch, E, that has a square notch or recess, 6, formed in its lower or straight edge or face, and at or near its outer extremity said latch is provided with a locking bolt or pin, F. The bolt or pin F is fitted in a tubular bearing, E, and has at one end a hand-hold, f, either in the form of abutton, Fig. 3, or a ring, Fig. 5, and at the opposite end the said bolt or pin F terminates in an enlarged head, f. The latter end normally projects out of the tubular bearing under the stress of a coiled spring, G, Fig. 2.

H is a lockingplate secured to sash-rail B. Said plate has a slot, h, and a wedge-shaped ledge or projection, h, the front and upper faces of which are curvilinear.

Instead of applying the locking bolt or pin F at ornear the outer end of the locking-plate or latch E, said bolt or pin may be applied about midway of the plate, as shown in Fig. 4, and engage a suitable slot in said plate.

The operation of the locker fastener may Serial No. 167,611. (No model.)

be briefly described as follows: When the locking-plate is in the position shown in Fig. 3 and is turned down, the head f ofthe looking pin or bolt F will engage the plate H, and

as the said latch is pushed toward the slot h the pin will be forced upward against the stress or tension of the spring G until the head of the bolt reaches'the said slot h,when the spring will throw it downward or forward,

as the case may be, and said bolt will belocked into position. At the same time the front and upper faces of the notch in latch E will engage the corresponding curvilinear inclined faces of the projection or wedge-shaped ledge h and force the two sashes together, thus forming a secure fastening therefor.

The fastener may equally as well be applied to doors, as shown in Fig. 4, or other structures, and it is not absolutely necessary to employ a springactuated locking-bolt, as a gravity or other bolt may answer the same purposes.

Having now described the nature of my said invention,and how the sameis to be performed, what I claim, and desire to secure by Letters Patent, is- 7 1. The herein-described lock or sash-fasten- 8o er, consisting of thelatch E, pivoted to asupport at an angle of or about fortyfive degrees with the under or working face of the latch, and a sliding locking pin or bolt connected to said latch, in combination with a locking plate provided with a slot for receiving the pin or bolt, substantially as and for the purpose specified.

2. The herein-described lock or sash-fastener, consisting of the latch E, provided with a 0 recess or notch, e, and pivoted or hinged to a support, 0 D, at an angle of or about fortyfive degrees with the under or working faceof the latch, and a spring-actuated bolt, F, connected to said latch, in combination with the 5 locking-plate H, provided with aslot, h, and

the wedge-shaped projection h, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence ofthe two subscribing IOO witnesses.

CHRISTOPHER LONGBOTTOM.
